Abstract

The power supply uses a switching transistor (TRP) and a transformer (UE) with its primary coupled via a series capacitor (CP) to a diode (DP) in parallel with a resistor (RP). A second series circuit connected in parallel across the transformer secondary (2) simialrly contains a capacitor (CS) in series with a parallel diode (DS1) and resistor. Pref. the second resistor is provided by a second transistor (TRS) receiving the capacitor discharge current to allow a current feedback via an inductor (LS) and a diode (DS2) for supplementing the operating voltage (UA).
